Объект StationAvailabilityList не имеет атрибута action

/ 03 августа 2020

Я написал настраиваемое разрешение, чтобы пользователь сделал запрос с ролью Владелец зарядной станции , чтобы иметь возможность выполнять все доступные действия в конечной точке, ['list','create','retrieve','update','partial_update','destroy']

мое разрешение: 

class IsChargingStationOwner(LoginRequiredMixin,permissions.BasePermission):
    message = 'You do not have the role of Charging Station Owner'
 
    def has_permission(self, request, view):
        if  request.user.is_authenticated:
            current_user = request.user
            current_role = current_user.role
            if current_role.name == "Charging Station Owner" and view.action in ['list','create','retrieve','update','partial_update','destroy']:
                return True
            else:
                return False

мое мнение: 

class StationAvailabilityList(generics.ListAPIView):
    serializer_class = StationAvailabilitySerializer
    permission_classes = [IsChargingStationOwner]

def get_queryset(self):
    #get the station owner
    station_owner = self.request.user
    #get the station id
    station_id = self.kwargs['station_id']
    #get the station
    station = Station.objects.get(id = station_id)
    #get the station availability records
    availabilities = StationAvailability.objects.filter(station = station)
    return availabilities

Когда я запускаю конечную точку, я выхожу с ошибкой: 

AttributeError: 'StationAvailabilityList' object has no attribute 'action'

Кто-нибудь может мне помочь разобраться, что происходит? Почему у меня нет доступа к конечной точке?

конечная точка: 

path('availability/<uuid:station_id>/', StationAvailabilityList.as_view(),name = 'station_availability_list'),
...
